We can’t always press a proper test specimen. In order to test rubber sheet material with AYO-IV, you can use a layered approach. Get a 3/4″ hole punch. As seen in the image, punch out enough round plugs so the total thickness is close to 1/2 inch. The idea is to put enough round plugs on top of each other to reach a height of approximately 1/2 inch. During AYO-IV setup, enter the actual height. In this case, the area is the same as a standard specimen: 3/4 inch. Thus, the area is the same as the standard specimen. Please note that this approach is not approved by ASTM D945; however, it is useful for comparing different sheet materials.
